If you are talking about the gasket for the top cover, it is a composite material. I doubt anyone could successfully replace one with the gearbox in the car for fear that some little pieces of the gasket might fall down into the gear reservoir. If you need to replace that, I did once by making my own gasket out of layers of cardboard gasket material (for carburators).

The donut shaped fibre gasket seal at the back of the gearbox is intended to keep gear oil from splashing back and leaking out when the car is accelerated from a dead stop. It is doubtful that it is the problem, but if you did need to replace it, the steering column would need to be removed.
